    Hexanol form intermolecular h bonding which is Weaker than intra molecular h bonding

    2Thank You

    Abc Efg 8 years, 2 months ago

    Both have OH groups so the effect cannot have anything to do with hydrogen bonding. I would say that the longer chain aliphatic structure has a greater surface area then the alicyclic molecule resulting in a greater degree of intermolecular dispersion force between its molecules, making the tendency to dissolve in water, which has only weak dispersion forces, less. Stickier molecule = less likely to gain energetic advantage by bonding to small unsticky molecules.

    The Williamson ether synthesis is a reaction that converts alcohols (R-OH) into ethers (R-O-R). ... The alcoxide can then be added to a suitable alkyl halide (typically a primary halide) to form the ether via an SN2 mechanism. Example: An example of the Williamson ether synthesis to make diethyl ether.

    Alkyl halides react with sodium alkoxide it form ether. Alkyl halides is 1 degree. Alkoxide ion is not only a nucleophile but also a strong base.so elimination competes over substitution and alkene will be FORM . If alkyl halides 2 or 3 degree.
